Toronto’s Drug Checking Service
Coordinated by the CDPE, Toronto’s drug checking service offers people who use drugs timely and comprehensive information on the composition of their drugs using the most sophisticated lab-based technologies.
People who use drugs in Toronto have long advocated for access to drug checking in an effort to reduce the harms associated with using drugs from the unregulated supply.
Launched in October 2019, Toronto’s drug checking service offers people who use drugs timely and detailed information on the contents of their drugs, helping them to make more informed decisions.
This drug checking service also helps to uncover the makeup of Toronto’s unregulated drug supply, which includes illegal drugs, as well as legal drugs diverted from regulated markets for sale through criminal channels. Visit the website for Toronto’s drug checking service to browse up-to-date and interactive information from samples checked to date. New information is published every other week.
How do I get my drugs checked?
Toronto’s drug checking service is free, anonymous, and available to everyone. Accepted samples include a substance (10 mg of a powder, crystals, rocks, or a pill, blotter, or a small amount of liquid) and drug equipment after it’s been used (a used cooker or filter, or leftover liquid from a syringe).
Samples are collected at five harm reduction agencies in Toronto where supervised consumption services are also offered:
- Parkdale Queen West Community Health Centre (Queen West site) – Bathurst and Queen
- South Riverdale Community Health Centre – Carlaw and Queen
- The Works at Toronto Public Health – Yonge and Dundas
- Moss Park Consumption and Treatment Service – Sherbourne and Queen
- Parkdale Queen West Community Health Centre (Parkdale site) – Dufferin and Queen
Results are available within a business day or two and are communicated to clients by harm reduction staff in person or by phone. Along with these results, clients receive tailored harm reduction supports, guidance, and referral to services (e.g., supervised consumption, naloxone training, primary health care).
How does Toronto’s drug checking service work?
Samples are transported from the harm reduction agencies where they are collected to a nearby laboratory at the Centre for Addiction and Mental Health or St. Michael’s Hospital to be analyzed.
Toronto’s drug checking service uses mass spectrometry technologies (gas- and liquid-chromatography). These sophisticated lab-based technologies offer detailed information about which drugs are found in each sample, along with some information about how much of each drug is present.
Toronto’s drug checking service is one of a few pilot projects that received funding from Health Canada to prevent overdose. This service operates by way of exemptions from the Government of Canada’s Controlled Drugs and Substances Act.
This drug checking service is being scientifically evaluated to understand its impacts on the health and well-being of people who use drugs in Toronto.

We acknowledge our service users, the members of our community advisory board, our partner organizations, and those that have lost their lives – both in the ongoing drug poisoning crisis and long before – due to policies of drug criminalization.
We acknowledge that the land on which we operate Toronto’s drug checking service is the traditional territory of many nations including the Mississaugas of the Credit, the Anishnabeg, the Chippewa, the Haudenosaunee, and the Wendat peoples, and is now home to many diverse First Nations, Inuit, and Métis peoples.
We acknowledge that racialized communities and survivors of colonization are disproportionately impacted by unjust drug policies. We strive to support the development of equitable drug policies that are responsive to the needs of racialized people who use drugs – including Black, Indigenous, and People of Colour – and their communities.
We acknowledge that many of the samples we check are linked to both fatal and non-fatal overdose, as well as adverse health events that impact individuals, families, friends, loved ones, and entire communities. We wish to acknowledge the people and pain behind the numbers we share.

Drug checking use and interest among people who inject drugs in Toronto, Canada
Drug checking services (DCS) provide information on drug composition to inform consumption practices and monitor unregulated drug markets. We sought to identify correlates of recent informal DCS use (e.g., fentanyl test strips) and willingness to use a formal DCS (co-located within a supervised consumption site and employing laboratory-based analyses) in Toronto, Canada prior to its implementation.View
